My work combines spatial design with deep expertise in colour, materials, and textiles. Previously, I was a Partner and Senior Interior Architect at Koi Colour Studio (2019–2025), leading projects for schools, kindergartens, offices, and private homes.

I hold an MA in Interior Architecture and Furniture Design from the Bergen Academy of Art and Design, and an MA in English Studies and Art History from the University of Copenhagen, specialising in Postcolonial Studies and Visual Art teaching.

My philosophy

Up here in Northern Europe, we spend most of our lives in man-made environments—predominantly indoors. As an interior architect, spatial designer, and colour specialist, my work is to make those precious square metres as functional and delightful as possible.

Our homes, workplaces, and institutions are significant investments with a real environmental impact. My goal is to make the most of what you already have, within the budget you set. This often means keeping, repainting, reupholstering, and refreshing existing materials, architectural features, and furniture, while carefully introducing new elements that suit your taste and respond to the architectural language of the space—so short-lived trends are avoided.

Together with my clients and collaborators, I create thoughtful, functional, and lasting solutions, with a positive impact all round.
